Specification of Letters Patent.

Patented Sept. 1, i914.

Application filed May 18, 1314. Serial No. 839,397.

f0 all whom it may concern:

. Be it known that I, WILLIAM S. HARLEY, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee '5 and State of Wisconsin, have invented certain new and useful Improvements in Oil- Distributing Mechanism; and I do hereby declare that the following is a full, clear, and exact description thereof. 1

My invention has for its object'to provide a simple, economical and .eflicient oil-distributing means for lubricating machine ele ments, the same being so constructed and arranged that by utilizing a novel adjustable pump mechanism the oil feed is predeterminedly regulated in proportion to economic consumption lVith the above and other objects in view the vinvention consists in what is. herein shown and described with reference to the accompanying drawings and. subsequently claimed.

In the drawings Figure 1 represents a seetionalifront elevation of an oil distributing mechanism embodying the features of my invention, the section being .indicatedby lines l1of Figs. 2 and 3 Fig. 2, a sec-- tional plan view of the same, the section being indicated by line 2-2 of Fig. 1; Fig. 3, a detailed sectional plan view through the mechanism, the section being indicated by line 33 of Fig. 1; Figs. 4:. and 5, detailed cross-sections through a valve mechanism employed in carrying out my invention, the sections being indicated by lines H and 5-5 of Fig. 1, and Fig. 6, a detailed longi-, tudinal sectional view through the delivery port and sight feed basin, the section being indicated by line 6-6 of Fig.1.

In the exemplification of my invention I have shown the same applied to the faceplate of a gear-casing fragmentarily illustrated, which gear-casing carriesatrain of gears constituting part of a motorcycle transmission fromthe source of power, all of which machine elements form no part of my present invention.

Referring by characters to the drawings,

1 represents the face-plate of a gear-casing 5o 2, which plateconstitutes a housing for a rotatory cylindrical valve-plug 2, the said valve-plug being fitted within a vertically disposed chamber 2 that is provided with a jacket lining-2", within which the valve- I plug has snug revolving fit. The upper and lower ends of the chamber 2" are provided with axially alined cones 3, 3, respectively,

' which form end journals for the valve-plug,

the upper cone 8 constituting a caprclosure for the chamber, whereby the valve-mechaof the valve-plug 2 is formed with a reduced neck that terminates with an eccentric head 4, which head constitutes the driving element for a reciprocative pump piston 5, the same being mounted within an obliquely disposed jacketed well 6, which well intersects the bottom portion of the valvechamber 52 to form a communicating pocket. The lower end face of the pump piston 5 is positioned to partially overlap the eccentric face of the valve-head 4; and is held in ennism is rendered accessible. The lower end gagement with the eccentric face by a coiled,

spring 7 which spring is incased within the upper portion of the well that constitutes an oil-reservoir. The spring is interposed between a shouldered upper end of the pump piston and a cap 'S, which cap forms a closure for the mouth of the oil reservoir, as shown. That portion of the lower face of the piston which is clear of the valve-head l, as shown,'is arranged to be engaged by an adjustable member, which member is in the form of a screw 9 that is in threaded union with the bottom of the well pocket. Thus said screw may be adjusted to raiseor lower the pump piston in opposition to its spring resistance, whereby the stroke of said pump piston is regulated, the maximum stroke of the same being in proportion to the pitch of the eccentric faceof the valve-plug'head. Motion is imparted to the valve-plug by means of a toothed section or pinion 10 that is cut into the body of the valve-plug above its neck portion and this-pinion meshes with a worm 10, which worm is carried by the hub of a gear-wheel 11, the said hub being 5 journaled upon a stud 12 that is supported by the rear wall of the gear-casing 2. The gear-wheel 11, as shown in Fig. 2,'consti-' tutes one of a train of gears 11, which gear-train is driven from a suitable source of power, not shown, whereby motion is incildentally transmitted to the rotary valvep ug. 7

Oil is fed to the valve chamber 2 from a gravity feed-pipe 13 through an inlet port 14, which delivery port is adapted to register with a peripheral segmental delivery groove 15 in the valveplug, the said groove being provided with a feed-aperture 15 that communicates with a longitudinally disposed the circuinference'of the same, as best shown in Fig. 1. The discharge groove 18 is arranged to effect registration once in each revolution of the plug with a discharge port 19 which discharge port communicates with a siglfit feed basin 20 formed in the face of the plate 1. The front wall of the basin is formed by a glass disk 21 that is secured by suitable gaskets and a gland in threaded union with said basin. The bottom of the basin belowthe mouth of the discharge port "19, is provided with a flow mouth 22, as best shown in Figs. land 6, which flow mouth communicates with theinterior of the gearcasing, whereby oil is distributed to the dethe discharge port with the sight feed basin 1 sired machine elements. By interrupting mentioned the efiiciency of the flow of oil can at all times beobserved. I The valveplug is also provided with a receiving and delivery groove 28, which groove, as best shown in Figs. 1 and 5, extends continuously about the peripheryof the plug in register with P pi ing, and delivery port 24, which port establishes communication between the well and valve chamber 2.

The peripheral receiving and delivery groove 23 is connected to the receiving and delivery duct 17 by. feed apertures 23, whereby the reservoir portion of the well is in constant communication with the inlet p ort 14.

From the foregoing description it is manitest that, with each revolution of the valveplug, when the delivery groove 15 registers with the inlet port 14, oil will travel from I 7 the source of supply downwardly through pheralgroove port 24. This the receiving and delivery duct 17 and from thence into the reservoir ing directed through the continuous peri- 23 and receiving and delivery feeding of oil to the reservoir extends through approximately one-quarter of a revolution of the plug, and, as the discharge port 15 passes the inlet port 141, communicatio'n is cut oi't from the source of supply. Following this cutting oii of the supply to the reservoir the eccentric head 4: of the valve-plug will start to lift the pump piston 5 and approximately coincident to the lift of said piston the discharge groove 18 of the valve-plug will be brought into register with the discharge port 19. The piston will thus,'in its lift, displace a preport 1 1.

ceiving and delivery with said well and cham er, a rotatory valve- 6' or the, well, bet ing a housing having a chamber therein prodetermined quantity of oil from the reservoir 6, which oil will be forced through the receiving and delivery port 24, peripheral groove 23 and from thence upward through the receiving and delivery duct 17 and into the sight-feed basin, from which it will'flow to the pointsvdesired to be lubricated. When the discharge groove 18 has passed the dis-- charge port 19, the flow of oil will be cut oil" from the basin and this cutting ofi ofthe flow will be followed by retraction of the pump piston through its spring resistance to the position shown in Fig. 1 and thus the cycle is completed. I

it is obvious tha't,should a smaller quan' tity of oil be required than that delivered by the maximum stroke oi": the piston, the said piston can be adjusted upwardly in such manner that its bottom face will only engage the eccentric face of the head 4: through a partial rotation of the latter. Hence it is apparent that predetermined measured quantities of oil are forced to their point of distribution and the supply ismaintained by gravity from the inlet I'claim: 1.
